AISI 1146 is a resulfurized carbon steel containing nominally 0.85% manganese and a range of 0.08-0.13% sulfur to make it free machining. It has relatively low hardenability. Its ductility and toughness are fairly good in the longitudinal direction but are low in the transverse direction. It is recommended highly for high-production automatic machine products. Among its many uses are axles and shafts, screws, spindles, ball joints, gears, bolts and bushings. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: CS-102. Producer or source: Carbon steel mills.
